To answer your question, Yes, KLM did fly
into Ottawa, from 1987 to 1992??.
The original flight landed in June of 1987 a hot
Wed. afternoon under cloudy, hazy skies. The air
craft that touched down was a 747-238 SCD, named
"Dr Albert Plessman". It departed for Halifax at
around 6:15 as KL676, on Wed, and Friday.
Over the next couple of years, KLM operated a third weekly flight, Wed-Fri-Sun. service. Eventually, the 747's gave way to Martinair's
The last flight was in March of 1992, a 767 of
Martinair. KLM ceased Ottawa service because the
route was not profitable.
I do have MANY photos I took of the 747 and 767
of KLM/Martinair when they were in Ottawa.
My favorite is the first flight into Yow on a
hot wed afternoon, especially when the viewing road quickly filled up with the curious waiting for the flying dutchman to touch down!!
